Also to understand the diagram, i would look at the video talking about light actually seen inside a black hole recently, suggesting parallel universes where white holes exist.

[@oracle372]

That is a good wisdom

[@Infinite_AM]

Well, we can see a black hole, weirdly, because we can see the light bending around it; we see it as it's effect on things we know how to see. A theoretical white hole doesn't necessarily have to constantly radiate light - perhaps it is also black. Perhaps light external to the white whole interacts with it in a way we cannot see it. We had to understand what a black hole was before we could see one, probably the same is true for a white hole. There may be qualities of a white hole that we have yet to understand, and until we know what to look for we won't be able to catch one.

Entropy only has to increase in a closed system. We have no way of knowing if anything outside of the observable universe is a closed system.

[@FutureNaught]

Nor do we know for certain that entropy will always flow in the same direction within our universe. For all we know, entropy could fluctuate back and forth like a sine wave but that phenominon would only be observable from a perspectice seperated from the flow of time as we know it.

[@davidfeliciano4329]

aFuturnaught Isn’t that a meaningless argument though? If the existence of something, anything really, is so outside our perspective as to be impossible to perceive and thus has no impact or bearing, then for all intents and purposes, it does not exist and is ultimately irrelevant to our laws. We can only create hypothesis and theories based on things we can observe, directly, indirectly, mathematically, etc. You could argue the whole ‘does a falling tree make a sound if no one is there to hear.’ But we know the answer because we know how sound works. If something is so far removed from us that we cannot ever interact with it, it might as well not exist.

[@davidfeliciano4329]

Bruno Pereira Yes, it is a very simple concept. Yet, that doesn’t fit here. If you cannot prove that a system exists, because it is literally outside of our perception/reality, then you can only continue to operate on the premise that it doesn’t exist. I mean you can BELIEVE that it exists all you want but, like Religion, that doesn’t make it real or even useable. You either work with what you have in front of you or you don’t.

[@davidfeliciano4329]

Bruno Pereira No that isn’t what I’m saying at all. If the system has ZERO affect on us or anything that we can observe in this universe or ANY other framework of a reality that we can interact with, then why would we waste time trying to prove such a system exists? I can say that outside of our observable universe, you can destroy/create energy. In our observable universe that isn’t true so changing the laws to accommodate the opposite isn’t going to help at all. There is no bias. I’m not saying it simply cannot exist, but if we cannot interact with it and it cannot be observed then we cannot formulate anything that takes it into consideration.

[@davidfeliciano4329]

Bruno Pereira I did not say that you said we should waste time nor was I trying to imply that you did. In fact, I did. Because I think it would be a waste of limited time and resources. Also, the guy that I was replying to essentially said, in a way, that we couldn’t when he said that the phenomenon could only be observed from a perspective outside the flow of time as we know it. That is, in essence, outside of our reality as we are governed by the flow of time as we do currently know it. Also I sense there is a mild misunderstanding in what I am trying to say. I’ll try to state it more clearly with what I am assuming you think I am trying to say and what I am trying to say: “If it is outside our reality, our observable universe, it cannot exist as it exist outside our laws.” “If we cannot observe something because it is outside of our observable universe, then we operate as if it doesn’t exist until otherwise.” I’m of the 2nd mindset. Why waste time and resources chasing something that has no evidence of existence? Now obviously the KEY note is something with no evidence can just be hidden in the math but usually there is something that hints at it. That is not what we are talking about that. Something completely outside our observable reality which has no impact or effect on us is a fool’s errand.

Well for one thing the big bang doesn't necessarily suggest the beginning of space and time, in some models it does but not in others. The math behind it can get a bit head-ache inducing but the difference is like that between dividing one by zero (Singularity) and having an infinitely small number. (Big bang) A big bang that was a singularity,in the sense of a black or white hole doesn't work since it is a center. What it would produce would also have a center from which everything would originate (and in some cases wouldn't produce anything at all. Why would the center of a black hole expand for example.) It's a subtle difference that's hard to explain, but it's an important one.

Four years after its release - I continue to love watching this episode… encouraged by all the current quests of science to explain white holes. I continue to, using my minuscule physics background, ponder the possibility of white holes (using Penrose diagrams and Schwartzshield metrics). Math May claim it’s “possible” however I can’t wrap my head around the possibility due to the second law of thermodynamics. Some theorize that white hole may originate at the singularity of a black hole, how can the gravitational force immediately convert to a repulsive force. I have concluded that a while hole is “possible” however, only at the merger/impact of two universes (M theory) 😉 Thank you Matt for the infinite knowledge provided. Cheers

So Hawking radiation is random virtual particle pairs spawning and taking away energy from a black hole, right? Does that mean hawking radiation of our mother-black hole, viewed in reverse, could be responsible for dark energy? Dark energy is just energy being added uniformly to our universe, after all. (Disclaimer: I also have no clue what I am talking about.)

[@Schindlabua]

Thanks for pointing that out! Although I have to admit I didn't get what he was saying, and baez himself says he doesn't know whether the pop-culture interpretation is even wrong. Anyway something radiates at least, so the question still stands. Would you know anything about that by chance? Do the numbers check out?

[@Schindlabua]

yrusb, I meant that since black holes radiate away energy, and our universe might have been caused by a white hole (which is a black hole with time reversed), maybe our "mother-black hole" radiating away mass could cause dark energy when viewed in reverse. I wasn't talking about the black holes in our universe, but I'll quickly edit that in

[@Schindlabua]

I don't know, that's why I'm asking. Since my question seems to be obviously stupid, let me ask another one, so maybe I can understand: What effect does hawking-radiation have on white holes? What effect does hawking-radiation have on the hypothetical baby-universes inside black holes? Radiation due to observer disagreement also means nothing to me, sorry. :/

That makes sense, thanks! I'm going to have to dive into some hawking radiation maths, it sounds super interesting.

Wouldn’t the event horizon appear as a “white hole” type boundary to an observer on the interior of the black hole?

[@betterlifeexe]

@Angelo Ferreira This ignores the possibility that they came into existence on the inside of the interior, like maybe us. This, I think would fit best with one of my favorite theories: Quantum Darwinism. I usually think about the version of quantum darwinism that allows other versions of Conway's game of life to be played out on differing systems, not strictly the field dimensions and relational data our local universe uses. In context with the black hole interior acting like a matter fountain for our universe, as some form of white hole or white hole cousin for reasons we don't yet understand... just think of them as singularities, and start presuming that singularities are just the natural cellular element that allows for vastly different internal and external 'spatial' relationships. (or properties of locality/nonlocality in qm) in that realm, particles and universes would be a constant emulation of cellular automata that dance out as our experiences of particles: ('particle pixels' 'multicellular quasiparticle life') in universe: ('white hole' 'birthing white hole like structures inside itself in the form of black holes').

@@chuckintexas I love the idea of matter-antimatter 'shells'.

[@MuammarThangkhiew]

"Very rare reductions in entropy do happen, as long as globally, entropy increases on average." So, does this mean that in order to decrease the entropy in a particular area, the entropy of some other area in the universe has to increase more than the average? So that's why my room gets so messy all the time. There's someone out there arranging theirs!

[@hindigente]

Not really. The increase of entropy is not some "first principle" of the universe, but rather a statistical consequence of the ergodic principle and boundary conditions of your isolated system. Now go tidy your room!

[@zacmilne9423]

Disorder is a misleading characterization of entropy so I wouldn't get too hung up on it. A better explanation of entropy is that it's a measure of how many ways the energy of the system of interest can be distributed amongst the available energy configurations or "microstates". As was mentioned in the video, entropy can decrease, it just very rarely does and whatever system had decreasing entropy will quickly maximize its entropy since things want to maximize the number of ways energy can be spread out simply because there are far far more ways for energy to be spread out than to be localized. In some highly idealized cases, entropy can be decreased by doing work on the system but the system in its new state will still obtain the highest possible entropy it can have.

[@frankschneider6156]

Entropy in a closed system can always decrease, it's just incredibly unlikely for it to happen.

As soon as I saw the half-filled penrose field, I saw the implications for white holes to be both star-like (the past of black holes) and like the Big Bang. It also seemed like, if we had a magical ship, we could enter the black hole and exit in the white hole, making it a form of one-way time travel. It could also be that every black hole has an exit as a white hole in a new universe. I think that could be plausible.

[@imjustheretomasterdebate8853]

Everything that goes into a black hole travels in time to the beginning of the universe. The only white hole we know of was the big bang itself. This is why all the information seems lost and it is impossible to see through a black hole. Even light is sucked into the distant past of the universe to meet the singularity of the beginning of time, the big bang white hole. And that's why everything is connected, past, present and future are consequences of each other.

[@TheEyez187]

@@neillpriest-fletcher1252 You're right, nothing can travel FTL through space. But the speed of light can be beaten. Like you said "Universal expansion" is one means. Quantum entanglement is another thing that is FTL, at least 10 to the 4th power faster, possibly instantaneous. Though visibly, physically observing and measuring both of these is difficult. Though an observable, measurable earthbound FTL also exists, in the form of Cherenkov radiation. Certain charged particles can pass through a dielectric medium faster than 186,292 mps (not sure by how much). But in doing so a blue (Cherenkov light) glow is emitted. It's basically the visual/speed of light equivalent of a sonic boom occuring when the sound barrier is broken. I'm kind of curious about gravity and FTL. Gravity, or its effects at least, move at light speed. But as it's a force (no matter/particles), it doens't have those constraints. The studies and research in to this topic following Newtons laws, Einsteins General relativity theory and others is really interesting; although testing such ideas is complex considering you'd really need something with a much higher gravitational force than our sun gives off! I'm also curious about whether the universe possibly spinning contributing to the universal expansion speeds. Moving your finger through 90''' in one second covers a distance of 15cms-ish. If your (unbreakable, unbendable) finger was a light second long (187,000 miles) and you were still able to move it through 90'', the end of your finger would have to travel much farther than a light second in a second; therefore FTL. Could use the same idea except with a spinning rope. 1rpm might not seem much, but if that rope (or galactic filament) is long enough, distances require FTL speeds. Higher dimensions (at least in my mind) may beat FTl as well. I think the above is it for FTL; well those and super-diarrhea! Sorry about the length!

If you drop a rock at mars, it'd drop faster and on earth the fastest. It wouldn't stretch or bend, just accelerate faster towards the ground. Meaning in reality that if you fall into a black hole, you'd just fall faster the further you go in the event horizon, sure you'd probably go unconscious because of all the blood going to the feet or if ur falling, all ur blood go into ur head. But you wouldn't die though.

Are whiteholes expected to grow over time due to reversed Hawking radiation?

TiagoTiago I don't think so. If they react in an opposite manner to black holes then they should shrink much faster. At least, my reasoning is that blackhole's increase in mass relative to the amount of matter that crosses their event horizon. So in the case of white holes, only when the rate of reverse radiation has overtaken the rate at which matter exits. That said, I still don't think they exist. Black holes aren't tunnels with an entrance and an exit. They're spherical singularities, and the entrance is their event horizon, which is a diameter around the central point. ¯\_(ツ)_/¯

[@IamGrimalkin]

No, white holes are tine-reversed eternal black holes, which don't have hawking radiation.

[@rafko250]

No nothing can enter a white holes event horizon, while nothing can leave a blacks holes event horizon. Meaning they cant grow with matter or energy form our universe, If i remember correctly hawking radiation is caused when a pair of virtual particles appears near the event horizon of a black hole, and one of the 2 opposite particles gets sucked in the other escapes. But i could be wrong its been some time since i brushed up on this stuff.

I have been thinking, what if we are inside a whitehole? Heres the reason: 1. Whitehole event horizon is a line in space where nothing can get inside. Now let's change out perspective as if we are in the middle of whitehole. Then, the event horizon is a line in space surrounding us in which when something past that line, it never came back. And nothing beyond that line can get to us. Sound familiar? Its perfectly describe the line of observable universe. It seems like observable universe line is just whitehole event horizon inwards! 2. Black hole happen when mass put in very tiny space. Even the tiniest mass can become black hole if it is compressed and dense enough to become a black hole. Now let's imagine the opposite, what happen in a infinitely huge space (actually we currently do). The universe expansion takes over which made galaxies accelerating away from us which led to the observable universe line! Blackhole very small space, whitehole very huge place.

[@taqiaufa7558]

3. In the Penrose diagram, whitehole comes from the infinite past. Now imagine a spaceship at the edge of the observable universe. Since it is moving away from us close to the speed of light, we will observe as if time freeze on them. Infinite time will past on us for them to to experience even a second. It seems as if we are ourself the infinite past.

Matt, I have one word for you on this subject (and I might have said it before, but I'll repeat it anyway): Alice-Through-the-Looking-Glass (1 word). "The looking-glass" part refers to distant singularity; Alice has her life partner (the counter-part) Bob; Alice implies Bob (and vice versa); "Alice" part is consciousness, "Bob" is (pure) information (in this metaphor), and the preposition implies point reflection. White hole is "information dual" of a black hole, and the artifact (one among the many) arises from GR only because physics doesn't treat the (purely digital) information properly. Note: This is fast-publishing thought, so it might be amended in the future…

[@puppy0cam]

The white hole could also help explain why the universe didn't instantly turn into a black hole when it formed. It's forcefully ejecting all of the matter in existence. This could not have possibly have happened instantly or the story would be that we are shrinking instead of the universe expanding. The question to ask is what would happen if a white hole were to form from inside a black hole. This is paradoxical because a white hole cannot allow things to enter while a black hole cannot allow things to exit. In order to resolve this, it expands space. Does space expand locally or "globally"? Because if it expands globally, then there is no friction to slow down the expansion. Like how if you were to throw a ball in space it would just keep floating forever. The universe may just exist in that space between two event horizons that have opposing rules. It is entirely possible that when all of existence was created by a white hole, after the white hole collapsed, then that universe simply formed a black hole. Then by random chance, when a new white hole formed, it formed inside a black hole. This could be how the universe as we know it came into existence. To end it off, I would like to say that perhaps a white hole is supposed to form within a black hole because since time is relative, you are more likely to encounter a white hole if your time moves slower.

[@zurviver_3747]

also, a black hole being a singularity... shouldn't it have less entropy?

[@sumsar01]

You require mass and gravity to form a black hole. At the big bang, the energy of the universe was too high for the fundamental forces to solidify. Assuming gravity is also such a force, then there wasn't any gravitational field so matter would not attract each other. There also wasn't any Higgs field so particles wouldn't have mass.

[@Cyberpuppy63]

"The white hole could also help explain why the universe didn't instantly turn into a black hole when it formed." - there was No matter, to begin with; just sub-atomic particles and "space time".

[@javiersaneiro6412]

Sub-atomic particles are also matter, just because they are sub-atomic does not means they are not affected by gravity. But in the early states of the universe there is another reason why it didnt collapse into a black hole, the matter has almost the same density everywhere, even with the matter of gallaxies in the space of one proton every point of space has almost the same amount of matter, the gravity net efect from all points of space is zero in that situation. There must be differents of density in the earlier universe, but just enought to make matter collpase to start to form galaxies after some thousands of years, it would need a bigger density difference to make all universe collpase into a giant black hole

[@DaleFrewaldt]

"The white hole could also help explain why the universe didn't instantly turn into a black hole when it formed." The opposite is actually true. Matter expelled from a White Hole would collapse back into a Black Hole because of self-gravity.

Lockout 469 this is a mathematical black hole that have been and will be alive for infinite time

[@manrightchea]

As I understand it, wouldn't a white hole require negative mass? Mass acts as an attractor in space. We also know that based on time dilation that time stops when approaching the speed of light. More specifically time stops at a point of zero mass like a photon. Therefore would seem to me that the only way for something like a white hole to exist would be for negative mass to exist. A white hole would have to mean a reversal of our temporal dimension and instead of being a point of infinite mass it would have to be a point of infinite negative mass.. a point where the effects of time dilation would be reversed as well.

[@deanreichel3621]

manrightchea Interestingly enough, the Wikipedia article for white holes implies they have, from what I gather, positive mass, and can attract objects from far enough away. en.m.wikipedia.org/wiki/White_hole The only explanation for this that I can wrap my head around is Hawking's idea (mentioned in the article) that the time reversed form of a black hole in thermal equilibrium is itself, another black home in thermal equilibrium. See my previous comment just a little bit below, where I imply that a white hole could create kugelblitzes at its event horizon. And that if both exist, they could always be present with each other, implying that the white holes created at a black hole's event horizons are *possibly* responsible for Hawking radiation. At least that's what I think.

[@StevanxoTutor]

It doesn't exist, from your explanation i realized that if time starts to go backward, we would see light going backward from the black hole which will now be white because consumed light is going backwards and black hole will then create star and everything would go backwards in past. So, it just time that goes backwards, nothing strange about this, except that time probably can't go backward.

Lister : [donning his fur-lined hat, again] ... back into the Universe? Kryten : Precisely. That's why we're experiencing these curious time phenomena on board. Lister : What time phenomena? Kryten : Like just then, when time repeated itself. The Cat : So, what is it? dialogue from Red Dwarf : White Hole (1991) (A British TV Series)

"...white holes are probably a figment of mathematical imagination..." - well, same Einstein thought about black holes :)

That end part is so scary - imagine falling into a black hole full of attorneys.

I know about white holes thanks to Red Dwarf

If a black hole is made by matter being overly squashed together, then wouldn’t a white hole be where a hole in space and time is ripped open?

[@OtavioFesoares]

Yes.

*Shoot. "White Holes." I totally misunderstood that. This isn't pornographic at all!*

There no black poles to go in them either. I feel cheated.

The event horizon is just the 4D topological inversion sphere for the momentum 4-vector of the universe on its world line through spacetime. The vector rotates more than 90 degrees when the tangent vector goes vertical and instantly approaches from infinity, from the other direction. When time is reversed, entropy is reversed. That explains it. There is no singularity. When the BH shrinks to the event horizon, it turns inside out. The minimum diameter of the universe is the size of the event horizon. After that, comes a white hole and a big bang. The whole thing is a single particle rotating in four dimensions. Each rotation is a penrose aeon. Time never switches direction. It's the same phenomenon as looking at a candle sitting at the edge of a rotating platter, from the side. The candle appears to be accelerating left and right, left and right. But from the overhead point of view of an extra dimension, you can see it's really rotating in N + 1 dimensions. No action is required, no acceleration. The arrow of time doesn't flip; it rotates. That's what the universe is doing.
